K&N SRI- any experiences?

[jonismyname]

hello all. last night i drilled about 8 1/2" holes strategically placed in the bottom of my airbox, and discarded my tuner tube, and currently have a kn drop in. i like it. but as is expected, small positive improvements lead me to want the real thing.

i would love a TRD CAI, but am not willing to pay $$ for new...
the simota appears to be a very excellent deal from kargoboy right now (if anyones hasn't seen the sale yet, look http://www.yarisworld.com/forums/showthread.php?t=13354 )

but i am a fan of kn filters, and wonder if anyone is familiar with the build quality of the SRI? kn claims 4.5hp gain, and backs up with a dyno...

that gain seems pretty fantastic, more than i've seen from other products, yet after my hours of research (constantly protested by my girlfriend... i should be doing chores instead of educating myself... GOSH) i find very little information about the kn SRI on here...

the price is a bit high at 300+, but i am an employee for a kn distributor (napa) and pay close to cost... id expect ~200

not to throw another line into the pond, but we also carry a shiny modular system that seems pretty well regarded... please feel free to reflect on these when you kindly respond...

sum it up: simota, KN, or build a fancy one.
simota-price is right. support vendor. others have tried it.
kn- build quality?! dyno backed. cost comes out of my paycheck... GF won't know.
build one- shiny. i call it my own. name it. put a "jon made this" sticker on it.
probably least expensive.

thank you for all your feedback
